Benefits of technology
The present invention provides an improved method and apparatus for joining multiple expandable tubular members. The invention involves a sleeve that is overlaid and coupled to the joint of two tubular members, with the sleeve having opposite tapered ends. The sleeve can be made of frangible material or have a variable wall thickness. The invention also includes a method of inducing stresses at selected portions of the joint and a sealing element for sealing an interface between the tubular members. The technical effects of the invention include improved strength and durability of the joint, increased axial compression and tension loading capacity, and reduced stress risers.
Problems solved by technology
Existing methods for radially expanding and plastically deforming tubular members coupled to one another by threaded connections are not always reliable or produce satisfactory results.
In particular, the threaded connections can be damaged during the radial expansion process.

Embodiment Construction
[0045] Referring to FIG. 1 in an exemplary embodiment, a first tubular member 110 includes an internally threaded connection 112 at an end portion 114. A first end of a tubular sleeve 116 that includes an internal flange 118 having a tapered portion 120, and a second end that includes a tapered portion 122, is then mounted upon and receives the end portion 114 of the first tubular member 110. In an exemplary embodiment, the end portion 114 of the first tubular member 110 abuts one side of the internal flange 118 of the tubular sleeve 116, and the internal diameter of the internal flange 118 of the tubular sleeve 116 is substantially equal to or greater than the maximum internal diameter of the internally threaded connection 112 of the end portion 114 of the first tubular member 110. An externally threaded connection 124 of an end portion 126 of a second tubular member 128 having an annular recess 130 is then positioned within the tubular sleeve 116 and threadably coupled to the inte...
